CARPET'STRETCHER.-

SPECIFICATION forming part of Letters Patent No. 579,130, dated March23, 1897.

Application tiled June 15, 1896. Serial No. 595,712. (No model.)

To @ZZ whom, t may concern:

Be it known that I, DENNIS J. CARROLL, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Carpet-Stretchers,of which the following is a specification.

The object of this invention is to produce a strong and easily-operatedmechanism for stretching carpets while putting them down on iioors.

In the accompanying drawings, which form a part of this specification,Figure 1 is a plan view of a carpet-stretcher embodying the features ofmy invention. Fig. 2 is a side elevation of the saine with its middleportion broken away.

Like letters of reference indicate corresponding parts in both views.

A is a preferably rectangular main draftbar.

A" is a groove formed in one side of the main draft-bar A. A2 is aracksecured in the groove A therein.

A2 A4 are screws securing the rack A2 into the groove A in the maindraft-bar A.

A5 is a stop xed in one end of the groove A in the main draft-bar A.

B is an anchor-plate.

B is a stud formed, preferably, integrally therewith and extendingthrough the main draft-bar A.

B2 is a pointed anchoring-dog projecting downwardly from theanchor-plate B.

B3 is a rivet extending through the anchorplate B and main draft-bar Ato secure the former to the latter.

C is a carriage through which the main draft-bar A extends and alongwhich it may be freely driven.

O' is a pinion mounted on the shaft O2 in the carriage O and meshingwith its corresponding rack A2. y

O2 is a crank for rotating the shaft O2 and its pinion C.

C4 is a detent pivoted to the carriage C and adapted to be engaged withor disengaged from the teeth of the pinion C.

D is adraft-tree provided with draft-hooks D', projecting from the underside thereof.

D2 is a rivet pivotally connecting the drafttree D midway between itsends on the under side of the carriage O, thereby permitting a freeoscillation of the draft-tree D thereon.

In operation the anchoring-dog B2 is driven into the door close to thebase-board by striking upon the projecting stud B'. The drafthooks D arenext caused to engage the carpet at a little distance from its edge andthe crank O2 turned. Operating the crank O2 willcause the pinion O' totravel along the rack A2, thereby driving the carriage O along the maindraft-bar A. By rotating the pinion O in one direction the carriage O ismoved toward the anchor-plate B and the carpet is stretched thereby, sothat its edge may be tacked down to the floor in the position desired,and to hold it when drawn taut until it can be nailed to the floor thedetent O4 is thrown :into engagement with one of the teeth of the pinionO.

The draft-tree D, being pivoted to the carriage C, is free to oscillateand thus accommodate itself to differing degrees of tension.

The projecting head of the screw A4 and the stop A5 limit the movementof the carriage O on the main draft-bar A by impeding the passage of thepinion O beyond the ends of the toothed rack A2.

I claim as my invention- In a carpet-stretcher, in combination, a maindraft-bar, provided with a longitudinal groove therein and two openingsthrough the bar near one of its ends, a toothed rack having holes forsecuring the rack in the groove, an anchor for engaging the fioor, saidanchor provided with a web having an opening therein for attachment tothe main bar, a curving spike integral with the web and anoppositely-extending pin for receiving blows, a carriage on the maindraft-bar, a draft-tree provided with draft-hooks and having a pivotalconnection with the carriage, a pinion for engaging with the rack havingjournalbearings inthe carriage, a supporting-shaft for the pinion, acrank for rotating the shaft, a detent for locking the pinion, and astop in the groove for limiting the travel of the carriage on therack-bar substantially as and for the purpose specified.
